Bravo! Kerry Washington, Allison Williams and Rosario Dawson led celebrations for influential women in Washington over the weekend. Not only did they speak up for their sex but they also pulled out all the stylish stops, proving that women really can have it all.

Kerry was right on trend in a red and black check babydoll dress with leather sleeves and black leather boots. Rosario opted for a super-feminine blue lace dress and nude peep-toe heels. Fancy.

And then there was Allison Williams who stunned in a classic LBD with detailed panelling effect and black stilettos. Let's hear it for the girls.

And in the name of all LBDs, our ultimate style staple, take a look through our gallery for a little inspiration.
